Look at the notes of the site from the ring https://darksouls2.wiki.fextralife.com/ ... rpent+Ring

full set increases souls gain by 25%

covetous ring adds 10% increase / ring +1 - 20% increase / ring +2 - 30% increase

Late reply but for anyone who stumbles upon this and wonders the same question, the tseldora cap=2.5% chest=5% legs=5% arms=10% therefore jester and tseldora arms give same bonus (10%).

200

it is multiplicative.
so full set would give : 105*105*110*102.5 % gain.
so about 24%

replacing the hood and robes with nahr alma should increase it a bit (to 33% : 1.05*1.105*1.1*1.1)
then multiply depending on which silver ring you use

The full set gives +24.3% souls per kill. The Silver Ring +1 gives +20% per kill. Combined, they stack multiplicatively for +49% souls per kill.

Sadly, no

After you kill him, buy it off of the hag merchant lady

what are you talking about? I always get it when he dies

No, it only affects the armours stats which are defence and resistances, the bonus that the armor gives is just an added extra.

wich means that you do not get benefits from equiping multiple pieces of the same set, but some pieces might have an effect on their own, i know you know and i know their phrasing is weird, the author probably thought everyone is used to set bonus with so many Rpgs using this mechanic

Maybe they mean equipping full sets doesn't provide a benefit. In RPGs you get a bonus when you equip a full set.

the only real reason to get this set
